Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Key value for chemical safety assessment
Additional information
Three acute toxicity studies of reliability 1 for Pigments Yellow 12, 83 and 170 on Danio rerio and Oncorhynchus mykiss are available. As could be expected from a grouping approach, for all three pigments of the Diarylide Yellow group consistently no toxicity towards fish has been found in any of these OECD 203 studies with nominal concentrations well above the solubility limit (0.4 µg/L).
Three further studies on pigments Yellow 13 and 83 are considered unreliable as suspensions of the undissolved test material were used as test solutions. Two of these studies showed LC50-values of 49.1 mg/L (pigment Yellow 13, VKI) and 18 mg/L (pigment Yellow 83, Hamburger). Toxicity was caused by additives in the test formulation. Therefore the results are not relevant for the assessment of the category substances.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
